Ipomoea (morning glory) is the largest genus in the family Convolvulaceae. Cultivation of morning glory plants began in the late Edo period in Japan, and this horticultural success resulted in thousands of plants with varying floral displays. In addition to the different flower morphologies, leaf shape is highly variable within this family making it an ideal group in which to study leaf develop...

We describe the Maple 23] implementation of multivariate factorization over general nite elds. Our rst implementation is available in Maple V Release 3. We give selected details of the algorithms and show several ideas that were used to improve its eeciency. Most of the improvements presented here are incorporated in Maple V Release 4. In particular, we show that we needed a general tool for im...

We conducted two experiments to determine the usefulness of a chlorophyll content meter (CCM) for the measurement of foliar chlorophyll concentration in sugar maple (Acer saccharum Marsh.) in the fall color period. In Experiment 1, four sugar maple trees were visually assigned to each of four fall foliage color categories in October 1998. On four dates in the fall of 1999, leaves were taken fro...

In autumn, maple trees disperse their seeds by employing autorotation under windy conditions. Maple seeds equipped with a small wing begin to autorotate within 1 m after they are detached from trees, and the autorotating motion generates the lift force that slows down its descent [1,2]. From measurements using digital particle image velocimetry (DPIV), it was elucidated that a stable leading-ed...

Abstract This paper uses the mathematical software Maple for the auxiliary tool to study six types of definite integrals. We can determine the infinite series forms of these definite integrals by using Parseval’s theorem. On the other hand, we provide some definite integrals to do calculation practically. The research methods adopted in this study involved finding solutions through manual calcu...

Observation This entire document is written in Maple 16; its related PDF file will be generated depicting the construction of a 4th-order accurate mimetic divergence, thus matching Appendix J of [3]. However, the interested reader can download this Maple worksheet, make necessary changes, and produce the appropriate tailored results: Please state the required order of accuracy (an even integer ...

Maple syrup urine disease (MSUD) is an autosomal recessive condition with an incidence of approximately 1 in 150 000 live births with a higher incidence amongst children from consanguineous relationships [1]. It is caused by an enzymatic deficiency with reduction in oxidative decarboxylation of branched-chain amino acids (BCAA) (leucine, isoleucine and valine) resulting in elevated levels and t...

Acer (maple) species and their horticultural varieties are world-famous ornamental trees with colored leaves that widely used in natural potted landscaping, as well gardening (Lin et al., 2015). Japan the United States breed most maple varieties, which hybridized or selected from A. palmatum, saccharum, rubrum, japonicum, shirasawanum, buergerianum, morifolium (Gao In recent years, China has be...

Cultivars of red (Acer rubrum L.) and Freeman maple (Acer ×freemanii E. Murray) are popular ornamental plants which are commonly placed in a variety of landscapes. To date, little information quantifi es the capacity to tolerate and recover from drought among cultivars of red and Freeman maple. The objective of this study was to compare the effects of water stress on the physiology of fi ve dif...
